Precipitated Silica as Paint Matting Agent used for Automotive Coatings
Description
1, Automotive Coatings is paint used on automobiles for both protection, decoration and refinish purposes. Automotive Coatings enhance the appearance and also protect it from extreme temperature, UV radiation, and foreign particles. Matte Finish is a low profile, non reflective finish that delivers superior coverage. Ideal for painting racing stripes or entire hoods in a matte black finish. Also great for grills, spoilers and other accessories.
2, Silica Matting Agent usually used for the Automotive Coatings. Silica gels can influence rheological properties, although other agents are typically preferred for rheological control purposes. With high porosity and strict control of particle size and particle size distribution, It provides a superior matting efficiency, excellent coating appearance and transparency, cost efficient, effective anti-settling agent and easy dispersion, smooth, abrasion resistant films of high surface quality.
Character
1, Super Matting Efficiency. The high purity silica and 1.8-2.0 ml/g Pore Volume as well as fine control of particle size and particle size distribution, it makes the paint film higher matting efficiency.
2, Excellent Transparency. The refractive index of silica is comparable to most resin systems.
3, Excellent Hand-feeling: These silicas have minimal effect on the mechanical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance.
4, Surface smoothness and improvement in scratch resistance: These silicas have minimal effect on the physical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance.
